There are many perks to being a twin. First, you are statistically proven to be more popular than your average twin-less peers. Second, you always have someone to party with. Third, when one twin goes missing, you can say he or she "looks exactly like me" when filing a police report. And, last but not least, you have someone to start a billion dollar empire with, just like today's 25th-birthday girls Mary Kate and Ashley Olsen.

We can't believe their a quarter-of-a-century old, either. It feels like just yesterday that we watching them talk about "outs cream" and say "You got it, dude" on Full House; it's easy to lose sight of the fact that Mary Kate and Ashley have not only become multimedia heavyweights but also undeniably sexy. We also sometimes forget that the Olsen twins aren't the only identical siblings who've gained fame by looking the same. Get ready to see double as we count down the 10 Hottest Celebrity Twins.
